MAT.

Original application filed May 25, 1923,

This is a division of my Patent No. 1,635,731, dated July 12, 1927, and filed May 25, 1923, bearing Serial No. 6&1,503.

My present invention relates to mats and more particularly to a flexible mat formed of separate frame members held together by flexible strands.

The principal object of my invention is to provide a flexible mat having a series of rigid 10 unconnected frames held together by flexible strandswhieh are wrapped around portions of the frames and preferably, though not necessarily, pass through the frames so as to form a mat having two Wiping surfaces be tween which the rigid frames lie.

Another object of my invention is to provide a flexible mat formed of a plurality of separate frames connected together by flexible strands which are looped around certain portions of the frames and pass therethrough in such a manner as to define open spaces for cleaning purposes while at the same time providing wiping surfaces on both sides of the mat.

With these and other objects in view which will appear as the description proceeds my v invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawing, Fig. 1 is a top plan view of my mat with portions of the wiping surface removed to show the separate frames,

Fig. 2 is a vertical longitudinal section taken on line 22 of Fig. 1,

Fig. 3 is a vertical transverse Section taken on line 33 of Fig. 1, and

Fig. 4 is a view similar to Fig. 3 but taken on line 44 of Fig. 1.

Referring more particularly to the drawing it will be seen that I have provided a series of separate rigid frames 10, 11, 12, and 13, formed with left hand side bars 14, 15, 16, and 17 and right hand side bars 18, 19, 20, and 21, respectively. The side bars are connected together by shorter end members 22 and 23,

respectively, which makes the frames substantially rectangular. The frames are substantially alike and may be made by butt-welding wire of an appropriate size. .WVhile I have shown four frames, yet it is to be understood that I may vary this number as desired.

The wiping surfaces of the mat are preferably formed of flexible strands of yarn or cord interwoven with the frames, certain of strand 31. After being looped around bar 18 Seflal 03- Divided and this application filed August 21,

the strands being indicated at 30, 31, 32, 33,

34C, and 35, respectively. The outside or selvage forming strand 30 may be looped around and fastened to the bar 21 of frame 13 as at 36 and then wound around the adjacent end frame 23 as indicated at 37, after which it is passed through frame 13 and-overbar 17. It is then passed under side bar 20 and'looped around the adjacent end member of frame 12, this process being continued until the strand has been wound around the end member of frame 10, after which it will be passed around andunder side bar 14 and extended through frame 10 and'o-ver side member 18 to form strand 31 will be passed over said bar 18 and under side bar 15 without being looped therearound, over and'around member 19, under but not around member 16, etc, being finally wound around member 21, after which it will be started back in the reverse direction as strand 32. This latter-strand will'be passed over and around bar 17 under'but not around bar 20, over and around bar 16, etc.,being finallywound around member 14, after which it will be looped back in the 'reverse'direction as strand 33. This proceedure will be followed until all the strands are in'place and frames filled, after'whichv the'end of the last strand may be secured to one of theframesin a manner similar to that by which the first end Was secured in'place. Odd'strands '31, 33, etc. are disposed similarly to each other with respect to the frames and the intermediateor even numbered strands are disposed similarly to each other.

I find that the mat will be flexible enough to permit cleaning and folding without losing its shape if the frames are spaced apart a distance substantially equal to the width of the frames and the diameter of the cords or strands is from a third to a quarter of this distance.

Reference to Fig. 2 shows that each stra-n is passed around alternate bars and toone Hm side of but not around the intermediate bars and that the strands are all passed through each of the frames, adjacent strands passing through the frames in opposite directions so t as to'define open spaces by means of which I 5 7 the mat may be cleaned. Also, adjacent strands in passing between adjacent frames cross each other so as to provide open spaces for the purposes of cleaning the mat. As shown herein, the odd strands are looped Ho around the interior right hand bars 18, 19, and QO'and under the interior left hand bars 15, 16, and 17. The opposite relation of these parts exist for the even numbered strands.

From the foregoing it willbe seen that I have provided a mat formed of a series of independent unconnected rigid frames held together by flexible .strands which pass through each frame and appear on both sides thereof to provide a mat having a wiping sur face on each side thereof. Also, it will be seen. that adjacent strands pass through and between the frames in opposite directions, thus defining open spaces through which dirt may pass, and that each strand is looped around one memberandpasses to one side of the other member of each frame being thus looped. around each frame at, but one point. While. I have indicated herein a, particular form of myinventiomsetting forth one method of. crossing the flexible strands and interweaving the same with the frames yet I do not wish to be limited to this particular arrangement as it is obvious to those skilled in the art that the principles set forth herein can be carried out without adhering strictly to the form of mat shown and described herein.

.What I claim is:

1. A mat composed of a plurality of separate spaced substantially rectangular rigid frames held together by strands of flexible material which are looped around one side of the frames and passed throughthe frame and under the other parallel side thereof and looped around said parallel side of the adjacent frame and passed through said adjacent frame and under the other side thereof.

. 2. A mat composed of a plurality of separate spaced substantially rigid frames held together by strands of flexible material which are secured to the outer side of one of the frames, passed thereunder and looped around the end of said frame and over the other side thereof and under the-side of-theadjacent frame, looped, around the end of said last mentioned frame and under and around the other side of said frame.

3. A mat having a plurality of spaced substantially rectangular frames held together by stantially rectangular frames held together by flexible strands looped aroundonesideof each frame and passing through each frame to present wipingsurfaces on each side ofthe frame. p

5. A mat having a plurality of. separate frames each composed of substantially parallel side members and flexible strands looped around the side members and passing through each frame to present wiping surfaces on both sides of the frame.

6. A mat having a plurality. of separate 1 I spaced substantially rectangular frames held together by flexible strands looped around one side of eachframe and whichextend across each frame and between the frames, top-resent wiping surfaces. on each side of the frame.

7. A mat composed of a plurality of rigid substantially rectangular frames held together by flexible strands, one of said strands being looped around the ends of said frames and the other strands looped about the side members of said frames and, extending through each frame and between the, several frames, to present wiping surfaces. side of the frame.
